You can install any transceiver supported by the PIC. For information about installing
and removing transceivers, see the PIC and Transceiver Installation Instructions.

■

Fiber-optic SFP transceivers:

■

Duplex LC/PC connector (Rx and Tx)

■

Optical interface support—see Table 21 on page 48

■

1000Base-T SFP transceivers:

■

Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45
connector

■

Pinout: MDI crossover

■

Length: 328 ft/100 m

NOTE: Do not install SONET/SDH OC48c/STM16 SFPs in the Gigabit Ethernet port. The port
will not recognize the SFP.

Cables and connectors

Status LED, one tricolor:

■

Off—Not enabled

■

Green—Online with no alarms or failures

■

Amber—Online with alarms for remote failures

■

Red—Active with a local alarm; router has detected a failure

NOTE: The green status LED is lit on the 2-port Gigabit Ethernet IQ PIC when at least one
port is online.

Port LEDs, one per port:

■

Off—Port is down

■

Green—Link is established
